Setting up for an illegal campus keg party.
Someone has spotted the Dean of Students coming and this guy is hurriedly trying to hide the evidence.
The guy in the orange shirt is yelling “Run!"

“orange shorts” I meant.

This photo shows a fraternity pledge participating in a rite of passage for becoming a Bonafide member of the Phi Delta Theta fraternity at Knox College. It is a race, where pledges must push a heavy, empty, oak whiskey barrel around a designated course using only their legs and feet. The victor is honored but the the true challenge is for all the pledges to finish this very challenging task.
